Using Enoch time frames, this formula is true to Pi to the 9th decimal of accuracy, (3.141 592 653 590 6). (An Enochian year is 364 days and a priestly cycle is 168.) The 22/7 is well known as an approximate of Pi, but 7/22 also relates to the 7th day of creation and the 22nd day (Tabernacles), and the radius as 3.5 days/years, etc. However, this formula is 1.6 billion times more accurate than 22/7 by itself. It demonstrates the extreme compatibility of Pi with the Enochian calendar
